We found the source of the ooze. A mix of dishwaher water, dish water, spray foam all fighting it's way out the bottom side of this spray foam.
Cracked right after the coupling.
I carved out some of the spray foam and used my Japanese Pull saw to cut out the coupling and prep for a repair.
I thought I might find a belly and perhaps this area was sagged and maybe froze but the pipe was perfectly clean. That's one positive so far.
